The Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) has been widely used as a technique that will allow a machine to distinguish between input from a human and that of another machine. The security of current CAPTCHA methods is not sufficient to protect against advanced modern malware. This paper focuses on applying gamification, the use of game elements in non-game human interaction systems, in order to improve the security and usability of CAPTCHA systems. We propose to use movie-based quizzes to achieve a Gamified CAPTCHA system that employs the human capability to recognize the strangeness of a short movie story.
